Oboz sawtooth walking shoes. Sportshoes.com have just decreased the price of these from £65, which was already the cheapest online price for the shoes. Price includes delivery. Various sizes available.

My pair, size nine, arrived today and they fit nicely. I've tried quite a few pairs of walking shoes recently and they all seem to be a bit loose in the heel. These fit snugly around my ankle with no heel slip. They're a bit lighter in colour than the pictures on the website.
